abstract

  • Formation and destruction of thermal stratification can occur under certain flow conditions in the upper plenum of sodium cooled fast breeder reactors (SFR). The flow patterns in the hot sodium pool of the upper plenum are very complex, including zones of free and wallbounded jets, recirculation and stagnation areas. The interaction of the sodium flow and thermal stratification has been analyzed experimentally at CEA in the years 1980-1990 in the SUPERCAVNA facility. The facility consists of a rectangular cavity with temperaturecontrolled heated walls where the flow is driven by a wallbounded cold jet at the bottom of the cavity. Experimental data of the temperature distribution in the cavity are available for steady-state and transient flow conditions. The experiments are analyzed with the CEA CFD reference code TrioCFD and the commercial code FLUENT by using …
